Problem Description：

People in Mars represent the colors in their computers in a similar way as the Earth people. That is, a color is represented by a 6-digit number, where the first 2 digits are for Red, the middle 2 digits for Green, and the last 2 digits for Blue. The only difference is that they use radix 13 (0-9 and A-C) instead of 16. Now given a color in three decimal numbers (each between 0 and 168), you are supposed to output their Mars RGB values.

Input Specification:

Each input file contains one test case which occupies a line containing the three decimal color values.

Output Specification:

For each test case you should output the Mars RGB value in the following format: first output #, then followed by a 6-digit number where all the English characters must be upper-cased. If a single color is only 1-digit long, you must print a 0 to its left.

Sample Input:

15 43 71

Sample Output:

#123456

解題思路：

這道題其實就是要求將3個10進制的數轉換成13進制的數並進行輸出。用str來存放每個數所對應的13進制下的字符。

AC代碼：

#include <bits/stdc++.h>  using namespace std;    int main()  {      string str = "0123456789ABC";  //每個數所對應的13進制字符      string result = "#";      for(int i = 0; i < 3; i++)      {          int temp;          cin >> temp;          result = result + str[temp/13] + str[temp%13];      }      cout << result << endl;      return 0;  }
